Sylvain Bauza 8abc7b47fd Modify the mdevs in the migrate XML
Now the destination returns the list of the needed mdevs for the
migration, we can change the XML.

Note: this is the last patch of the feature branch.
I'll work on adding mtty support in the next patches in the series
but that's not a feature usage.

Instances using vGPUs can now be correctly live-migrated by the libvirt
driver between compute nodes supporting the same mediated device types used
by the instance. In order to be able to do this, the compute hosts need to
support at least the minimum versions of libvirt-8.6.0, QEMU-8.1.0 and
Linux kernel 5.18.0. If operators use multiple vGPU types per compute, they
need to make sure they already use custom traits or custom resource classes
for the GPUs resource providers and that the instance was created with a
flavor using either a custom resource class or asking for a custom trait in
order to make sure that Placement API will provide the right target GPU
using the same mdev type for the instance.
